To all whom it may concern:

Be' it known that I, JAMES B- BATEMAN, a citizen of the United States of America, residing at Arlington, Hudson County, New Jersey, have invented new and,useful Improvements in Advertising-Display Cards, of which the following is a specification.

For advertising and other purposes it is often desirable to display a picture or printed matter, or a combination of the two, both by day and by nightfiand it may be desirable toplace the picture'in such a location that the only safe, practical or feasible 1 wayof illuminating the picture is from behind. 1

In such circumstances it has been customary toreproduce the picture orother matter as the case may be upon paper or other material of suificient opaqueness so that the picture is readily visible 1n the daytime by reflected light, such material being, however, thin enough to permit of the picture being displayed at night when illuminated by light transmitted from behind. This method has never given entirely satisfactory results, for the reason that when a strong enough light is placed behindthe picture to illuminate the picture sufficiently to make 7 it useful for advertising purposes, the intensity of the light tends to destroy the contrast between the shadows and the high lights, and the picture. is not displayed as satisfactorily by the transmitted light as in the daytime by reflected daylight.

Of course transparencies have been made I uplon glassbr other transparent material,

ich give very good results when displayed by illumination from behind, but these are not satisfactory} when viewed \by reflected light. I

The object of my invention is to produce an article suitable-for these uses which will vention, with parts broken away to show give an equally satisfactory display of the picture by. reflected daylight, and by trans.

mitted artificial light.

Inthe accompanying drawings '1- have shown by way of illustration a preferred embodiment of my invention. In these drawings similar reference characters designate corresponding parts in all views.

Figure 1 is a front view of a picture or advertising display card embodying my inthe several layers;

'ngig, 2 shows the card arranged for use;

Fig. 3 is a detail showing on an enlarged scale a section on the line 3-3 of Fig. 1. Referring to these drawings, I make first a picture 1, which may be a photograph, or advertising display matter, and may be black and white'or colored asdesired. This picture is made upon a suitable paper having sufficient opaqueness so that the picture will be clearl displayed by reflected light. I then ma e upon photographic film 2 another picture identical with the first, being a positive, and not a ne ative print, so that the high lights and she ows in the film positive are the same as in the main icture 1, and not the reverse thereof as is t e case in the usual film negative. In preparing-these pictures -manner indicated, I make up what I will call for convenience an advertising display card in the following manner:

for use in the I take first the film positive 2 and afiix to v the back thereof a piece cinch-inflammable, transparent cellulose sheet material or stock 3 of the sort frequently used for enclosin pictures and the like, the stock being re erably of about 5/1000 of an inch in t icknes's; and afix a sheet of similar stock 4 to the front of the film positive, so that the film 2 is encased in and protected by the transparent cellulose material. I then place over this the picture 1, andholding picture up to a source of light which passes through the film positive 2 and the plcture itself, I adjust the position of the picture upon the film positive until these coincide exactly, and then apply cement at the corners to hold the picture in this exact position until the roduct is finished.

'I then p ce these parts upon a piece of the same stock 5 of about 15/1000 of an inch:

thickness, and placea similar piece of stock 6 upon the whole, putting them ina press in the usual manner to form a ri 'd plate 'or card, the icture 1 being plain y visible in reflected light throu h the upper piece of transparent stock, an the icture being also visible when light is place behind the same,

the efiect of thefilm positive being to add depth to the shadows while interfering not at all "with the high hghts, so that thestronger the; light .that is placed behind the pictureythemore clearly 1 is the contrast the film and Letters Patent is:-

brought out, and the efiect when viewing the picture from the front with light trans mitted from behind is practically identical with the effect when viewing the picturefroma front reflected light only.

The use of the transparent stock and the methods of causing it to adhere to the icture, and of treating the surfacethereo as with silk to roduce a moir finish if desired, being 0 d and known to those skilled in lthe'art, I have notdescribed these in-detai 1 What I claim and desire to secure by J 1. An advertising displa card comprisin a picture clearly visible by reflected lig t, and a positive print of the same picture on transparent material placed behind and coincident with the aforesaid picture to enhance the contrast when viewing the picture by transmitted light; and trans arent means for holdin said pictures in ed relationship, andrigld 'for handling.

2. An advertising display card coin rising a picture clearly visible by reflected llght,

and a film positive of the same picture placed behind and coincident with the afore tures in fixed relationship, and rigid for handling.

3. An advertising display card comprising a picture clearly visible by reflected light, a positive print of the same picture on transparent material, a sheetot transparent protective material'secured' to each side of said p0sitive,- said positive being placed behind and coincident with aforesaid picture, and further sheets or transparent protective material encasing said parts.
